SELF-PROPELLED PLOW'ING-MACHINE.

Specification of Letters Patent.

Patented ug. 25, 1914.

- Application filed April 30, 1910. Serial No. 558,562.

To all whom it may concern:

Beit known that I, EDOUARD MARIE QUEL- LENNEC,- of 10 Rue de la. 'Chalse, PZLIIS, France, engineer, have invented a new and useful Improvement in Self-Propelled Plowing-Nachines, which improvement is fully set forth in the following specification.

This invention relates to "self propelled plowing machines or diggersin which the revolving tines. or diggers can be made to penetrate more'or less deeply intothe soil or be taken out of action when traveling along a road.

The. improvements relate more particu-- larly to the method of suspending and driving the harrowing or diggingtools and regulating and controlling the depth of tillage.

In the. accompanying illustrative drawings: lligure 1 is a side elevation of a machine embodying my invention; Fig. 2 is a plan thereof, some of the parts being removed; Figs. 3 to 6 are respectively a side elevation, a plan and a section at right angles to the axes and a section through the axes of the mechanism by means of which the driving chains act upon the harrowing or digging tools. Fig. 7 shows a detail.

1 is a harrow or digger of the type for example shown in my application Serial No. 558,561, of even date herewith, carried by a horizontal shaft 2 suspended at each end on an arm 3. The arms 3 turn about a shaft 4, carried by the frame 5 of the machineand situated between the front and rear wheels 6 and 7 At a certain distance from its point of attachment to the frame, each arm 3 is providedwith a hollow shell 8, perforated at its upper end to give passage to a rod 9 having upon it a racl: 10. Along the rod 9 slides apart 11 rounded at its upper end so that it may function as a swivel and suitably bear at'allpositions of the rod 9 against the concave surface of the shell 8.

The vlo rer surface of the piece 11 bears against a strong spring 12 'WhlCll bears.

against a sleeve 13 retained by the head 14 in which the lower end of the rod terminates. The racks 10 mesh with pm ons 15,

. each keyed to the end of a horizontal shaft 16, carried by the frame 5. Upon the frame 5 is also mounted a motor 17, Fig. 1, driving through asuitable change speed gear 18, a shaft 19 carrying at each end a chain wheel 20. A chain 21 connects each wheel to another wheel 22 keyed to an intermediate shaft 23. In 1 the motor isarranged longitudinally, but 1t may be arranged transversely, movement to the shaft 23 being then transmitted by other suitable gear. The sh'aft23 carries a toothed wheel 24 which meshes with a toothed Wheel 25 fast with the shaft 4.

To the shaft 4 and at each end of the same is fixed a chain wheel 26. The wheels 26 are each connected by a chain2 to a wheel 28 keyed to the shaft 29, mounted in such a manner as to be able to rotate in a casing 30 carried by the shaft 2 around which the easing canoscillate. The shafts v29, each carry a pinion v 31 which pinions mesh with toothed wheels 32 fast with the shaft 2. The casings 30 are provided at their upper ends with a handle 33 which allows them to be oscillated in one direction or the other around the shaft 2 for the purpose of setting the chain 27 at a suitable tension. The casings. can be kept rigid in the required position by means of slides 34 jointed at 35 to the arm 3; tightening bolts 36 slide in a groove in said slides and are moreover provided with heads which pass into slots in the casings 30. The slides 34 carry on their face situated near the casing, teeth 37 into which mesh corresponding teeth on the easing. By loosening the bolt 36, thetwo sets of teeth can slide upon each other without entering into engagement. When, on "the contrary, the bolt is screwed up (the casing being in the required position I it is rendered completely rigid. The shaft 23 also carries a toothed wheel 38, which gears with a wheel 39 on a shaft 40, mounted in a casing 41, carried by the frame 5. Upon the shaft 40 is mounted idly a bevel pinion 42, which gears with a' bevel -wheel 43, keyed on a horizontal shaft 44, also mounted in the eas- -ing 41 at right angles to the shaft 40. A prolongation of; the shaft 40-carries a hollow pivot 45, upon which turns idly a bevel pinion .46, also meshing with the wheel 43. The pinion 42 is provided'with catches 42 and the pinion 46 with catches 46*. A rod guided in such a manner as to be able to turn in the pivot and penetrating within the shaft 40 which drives it, carries a sleeve 48 provided with clutches which can be put into gear either with the pinion 42 or with the pinion 46, which has for effect to drive either one or the other of these pinions, thus imparting to the shaft 44 a movement of retation in one direction or the other. The rod 47 may be moved by an oscillating lever 49 through connecting rods 50 and a lever 51 all controlled bya handle 52. The shaft or the other, and the rods 9 move upward racks 10. These rods thus raise or lower the harrow 1. through the arm 3, the chains 27 preserving or downward through their the same degree of tension. because the axis of oscillation is also that of the shaft of the wheels 26 over which the chains pass; there is thus a'conve'nient and rapid means of raising or lowering the tines or digger tools.

The racks 10 are maintained in contact with the pinions 15 by means of rollers 56, each fast with one arm of a fork rocking on the pinion shaft 16, so that the rollers 56 can follow all the movements of the racks 10. Lastly the whole assemblage, arm 3, shaft 2 with harrow 1 and rods 9 with racks 10, is

guided by the aid of the curved grooves 58,

which have their centers at 4t and in which engage the heads of the pins 59 fixed to the.

arms 3.

Upon the shaft 4a is keyed a chain wheel 61 to a wheel 62. mounted upon a shaft 63, parallel to the At" its other end the shaft 63 has upon it a small bevel pinion 64 gearing with another: bevel pinion 65, fast with, a vertical screwfl threaded rod 66'along which can move an indicator nut 67, which moves in front of. a scale (38. The movements of the indicator 67 being proportional to the move connected by, a chain shaft A: and carried by the frame 5.

nients of the arm 3 and of the harrow, this indicator always shows the position of the tines. lhe driver can therefore regulate the depth of tillage and constantly control it without moving from the machine; he may also raise for a moment the tines in order to avoid an obstacle encountered in working the so l and lower it immediately after-- ward to the depth required.

The jointing of the arm 3 to the frame 5,i axles reduces to a great between the two degree the amplitude of the movements due to the inequality of the ground, and the method of suspending the harrow upon. springs as above descrlbedgives it sufficient liberty to follow the inequalities of the soil and even to give if necessary to an obstacle formed by a body too solid or too hard to be cut or removed.

As the arms 3 are jointed to the frame 5,

outside the rear wheels, the plowing device or assemblage of digger tools as a whole may be given as great an axial length as desired and in all cases a length greater than the distance between the outer edges of the the intermediary of a,

flanges. of the wheels which obviatesthe necessity of the wheels passing over tilled soil. 7 v

. The arrangements described are. only given. by way of illustration andmay be largely modified, for example between the shaft 23 and the shaft l actuated thereby, there may be interposed an arrangement allowingthe speed of rotation of the tines to be modifiedaccording to the speed of the vehicle, the conformation of the ground to be tilled, etc.

Having now and in what manner t 'liesame is to be performed, I declare that whatl'claim is 1. In a self-propelled plowing machine, the combination, with a, vehicle, *a pair "of side arms fulcrumed'on the'vehiele toswing in a vertical plane, a rotary digger shaft "particularly described and ascertained the nature of my said invention said worm-wheel, a reversing geartransmission mechanismintermediate said motor and the worm and arranged to drive the latter, manually controlled means for throwing the reversing gear transmission mechanism into or out of operation, rod, means for driving said rod at a speed proportional to the speed of the rack-engaging. gears, alnut on the screw-threaded rod, and a level orpositionindicator actuscrew-threaded ated by the said nut wherebythe relative height of the'diggers is indicated.

2. In a self-propellingplowing machine,
